High-Grade Lithium Drill Results At Lake Johnston

Charger Metals NL (ASX: CHR, “Charger” or the “Company”) is pleased to announce further high- grade lithium intersections from its maiden drill programme at the Medcalf Prospect of the Lake Johnston Lithium Project, Western Australia.


  • Further assays have been received for the maiden reverse circulation (RC) programme completed earlier this year at the Medcalf Prospect of the Lake Johnston Project, WA
  • High-grade lithium results returned from spodumene-bearing pegmatites, with significant intersections including:o 4m @ 2.06% Li2O from 145m (23CRC013)
    • 6m @ 1.56% Li2O from 19m (23CRC006)
    • 5m @ 1.41% Li2O from 83m (23CRC007)
    • 6m @ 1.34% Li2O from 24m (23CRC003)
    • 6m @ 1.06% Li2O from 47m (23CRC002) 1
  • The drilling at Medcalf has delineated a swarm of stacked spodumene-bearing pegmatites up to 13m thick (down-hole)within a 100m wide corridor 2Spodumene mineralisation has been intersected along 700m of strike and 250m down- dip and remains open in both directions 2
  • Assays for the final eight drill-holes are still pending, with results expected in the coming weeksPreparations are underway for a follow-up drill programme to test for extensions to the high-grade lithium mineralisation
Charger’s Managing Director, Aidan Platel, commented:

“We are very pleased with the results received to-date from Medcalf, with the high-grade lithium intersections correlating well with the logged spodumene-bearing pegmatite intersections. The swarm of stacked pegmatites remains open down-plunge, and we look forward to modelling the results once they are all received in order to plan the next phase of drilling to test for extensions of the high-grade lithium mineralisation.

 

These exciting results from the first drill programme at the first of many prospective target areas of the Lake Johnston Project really highlight the potential for the project to host significant economic lithium mineralisation.”

Assays have now been received for the first thirty-three drill-holes of the maiden RC drill programme completed earlier this year at the Medcalf Prospect. High-grade lithium was intersected in the majority of drill-holes to-date, correlating well with the intervals of spodumene-bearing pegmatites logged by the Company’s geologists. Significant intersections from the drill programme to-date include: 3

  • 4m @ 2.06% Li2O from 145m (23CRC013)
  • 6m @ 1.56% Li2O from 19m (23CRC006)
  • 5m @ 1.41% Li2O from 83m (23CRC007)
  • 6m @ 1.34% Li2O from 24m (23CRC003)
  • 6m @ 1.06% Li2O from 47m (23CRC002)
  • 5m @ 2.55% Li2O from 68m (22CRC002)
  • 6m @ 1.52% Li2O from 26m (22CRC005)
  • 5m @ 1.86% Li2O from 24m (22CRC007) and
  • 4m @ 1.83% Li2O from 56m (22CRC007). 4

The lithium mineralisation at the Medcalf Prospect is hosted within a swarm of anastomosing to tabular stacked pegmatites hosted within sheared amphibolite. The pegmatites are members of the lithium-caesium-tantalum (LCT) pegmatite family (albite-spodumene type) and spodumene has been logged in both the drill chips and in many outcrops. Spodumene is the preferred mineral for the commercial production of lithium, which is one component of modern lithium batteries.

The spodumene-bearing pegmatites are up to 13m in width (allowing up to 2m of contiguous internal waste) and have been delineated on a northwest – southeast strike over 700m long. The pegmatites dip at approximately 40° towards the southwest and currently remain open along strike and at depth (Figures 1 and 2).

Assays for the remaining eight drill-holes of the maiden RC programme are expected over the coming weeks. Upon receipt of the final assays the Company will model the pegmatites in order to plan follow-up drilling to target extensions of the high-grade lithium mineralisation.

Ekin Ober on Why AI Could Be Mining’s Most Valuable Tool Yet

For Ekin Ober, bringing generative artificial intelligence (AI) to the critical metals sector through her work at Aethos Labs wasn’t just about technological innovation — it reshaped how she thinks about strategy and sustainability in mining.

Now a principal at Kinterra Capital, Ober applies that broad, cross-disciplinary lens to investment decisions, emphasizing the importance of digital fluency, stakeholder alignment and long-term viability.

Her experience helps her identify operational bottlenecks and social license challenges early — essential in guiding assets like nickel and copper projects from concept to production.

Chris Berry: The West Must Invest in Refinement Now or Fall Further Behind

China’s grip on the battery metals sector has drawn increasing scrutiny in recent years as nations confront growing concerns around supply chain risk and resource security.

Through a blend of domestic output and aggressive overseas investment, particularly in Africa and South America, Chinese companies now command a significant share of upstream supply.

The country is responsible for roughly 60 percent of global rare earths production and controls over 70 percent of cobalt supply through its stakes in mines across the Democratic Republic of Congo.
